Title: Electron beam device
Inventor: IWASAKI YUTAKA
IPC: H01J37/244
Filed: 1986-06-18
Abstract: PURPOSE:To measure the surface voltage of a local part of IC with high precision by a method wherein a voltage corresponding to the maximum point of curvature of a detected, collected current intensity versus decelerated field voltage curve obtained by measuring the secondary electrons discharged from an irradiated part of IC using a decelerated field type spectroscope is detected. CONSTITUTION:A specimen 6 such as IC, etc., is irradiated with primary electron beams using an electron gun 1 to collect and detect secondary electrons discharged from the irradiating points by a detector 3 through a grid-type decelerated field electrode of a decelerated field type spectroscope 2 impressed with decelerated voltage generated by a decelerated voltage generating power supply 4. A voltage at a local part can be measured by a difference between the decelerated field electrode voltage V corresponding to the peak of a differential S- shaped curve A attained by collecting the secondary electrons discharged from the local part and the similar peak voltage Vp at a part kept in a reference voltage. Through these procedures, the surface voltage at a local part of IC can be measured with high precision.

Title: Vacuum forming tube for resin pipe molding
Inventor: WADA HIROSHI
IPC: B29C48/90
Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To remove the adhesion of foreign matter to an inner face and make the appearance presentable by providing a a vacuum suction hole or a vacuum suction groove on the inner peripheral face of the main body of a cylindrical vacuum forming tube and also providing an annular groove on the inlet side and a plate for removing foreign matter with an open part of almost the outer shape of a pipe across the annular groove. SOLUTION: A PVC parison P extruded from an extrusion molding die D shows a deposition of part of a heat stabilizer and a lubricant contained in a blended composition on the surface due to the slight cooling of the surface exposed to an atmosphere prior to the arrival of the parison P at a plate 12 for removing foreign matter. However, the part of the heat stabilizer and the lubricant is removed to the outside of the plate 12 by sliding into contact with the open part 13. In addition, if the parison P advances, it is quenched by a cooling water in an annular groove 14 and the foreign matter falls into the annular groove 14, although the former deposits on the surface, to be finally delivered from a foreign matter discharge port.  Consequently, it does not ensure that the foreign matter adheres to the inlet side of a vacuum forming tube 10 and moves to the inner face of a main body part 11, and that the stacked foreign matter scratches or streaks a finished product pipe or adheres to and stacks in a vacuum suction groove 15.

Title: Delay circuit
Inventor: TAKAHASHI AKINORI
IPC: H03K5/13
Filed: 1983-08-04
Abstract: PURPOSE:To obtain a delay circuit whose delay time is varied easily and stable against power supply fluctuation and temperature fluctuation by obtaining an injector current through the constant current source constitution using an operational amplifier. CONSTITUTION:An inverter consists of I<2>L logical elements Q6, Q7 and the element Q6 is activated by injecting an injector current to the emitter of the element Q6.
